Can I replace the drain plug on the bottom of the 1720 turbidimeter with a valve and permanent pipe to drain?
Summary
Hard plumbing drain for 1720 turbidimeter is not recommended, use the drain funnel accessory (p/n 9142000)
Answer

The drain connection on a 1720E turbidimeter body is a 0.5 inch hose barb.  Hach would not recommend hard plumbing this to a drain as this creates an opportunity for damage if the drain were blocked or had backpressure.  There is a drain funnel accessory that could be used (p/n 9142000) which would be recommended if the customer wishes to proceed with this plan.  Please see the attached instruction sheet which is included with that kit.
